Hi Murat,

Personally, I would re-think the tapped horns being physically incorporated with the rest of the system.  To start, from what I understand (I don't use a tapped horn) because they use both the front and the rear of the driver for sound, they have a time alignment that wanders a little with frequency.  I concede that it is low bass and that we are supposedly not that sensitive to bass time of arrival in small rooms but it is what it is.  But that little thing is nothing compared to the elephant in the room:  it does not matter how good your bass solution is if it not placed into the room properly.

The room OWNS the bass below 200Hz or so.  There is no way around this as the wavelengths of the frequencies become larger than the room dimensions so we get room nodes and so on and so forth.  You can be fortunate like Romy and have a lower bass line array that fits into his room at the speaker position...but that is not very common.  Most people have to move their lower bass around in the room so the the room nodes do not occur at the listening position/s.  This may include just one bass source or three or more with them placed at odd spots in the room.  The thing is that you just don't know until you put your bass source in the room and experiment.

If you have a regular rectangular room, you may be tempted to try a Double Bass Array.  It will require DSP to run properly, but it does get rid of room nodes which may go a long way toward a sound that can be tailored to your requirements.  Have a look at the first post here for a brief explanation of the concept.  How does it sound?  Don't know, but I have a feeling that as we take the room further out of the equation we are more free to work towards our own requirements for sound.

Regards,

Anthony
